Atossa Therapeutics Secures FDA Rare Pediatric Disease Designation for (Z)-Endoxifen
Atossa Therapeutics, Inc. (Nasdaq: ATOS), a clinical-stage biopharmaceutical firm specializing in oncology, announced today that the U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease (RPD) designation for its investigational drug, (Z)-Endoxifen, aimed at treating Duchenne Muscular Dystrophy (DMD). This significant designation not only amplifies the importance of (Z)-Endoxifen in addressing a critical pediatric health issue but also potentially positions Atossa for a Priority Review Voucher (PRV) upon regulatory approval.
Understanding Rare Pediatric Disease Designation
The FDA's RPD designation is assigned to drug candidates targeting severe or life-threatening illnesses that primarily affect individuals aged 0-18. Once a marketing application receives approval, drugs bearing the RPD designation may qualify for a PRV, granting expedited review for subsequent applications, or may be traded to other sponsors. Recent data indicates that PRVs have sold for as much as $160 million.
Significance of the (Z)-Endoxifen Designation
Dr. Steven Quay, President and CEO of Atossa, emphasized that gaining RPD designation is an essential milestone for the company, underlining the scientific credibility of (Z)-Endoxifen as a treatment for DMD. He stated, “This designation is a strong validation of the science supporting the potential of (Z)-Endoxifen as a treatment for Duchenne Muscular Dystrophy. Families urgently need better options beyond steroids and gene-targeted approaches.”
Dr. Quay pointed out that while Atossa's primary focus remains oncology, this milestone illustrates (Z)-Endoxifen's potential as a platform therapy for both cancer and rare diseases, which could yield significant non-dilutive value through the RPD initiative.
Development Path and Advantages of (Z)-Endoxifen
Janet Rea, Senior Vice President of Research and Development at Atossa, highlighted that the RPD designation will foster enhanced interactions with the FDA as they shape the clinical development plan for DMD. Rea expressed optimism regarding preclinical data, suggesting that (Z)-Endoxifen may offer a unique therapeutic approach as a potent Selective Estrogen Receptor Modulator/Degrader (SERM/D). She noted that unlike newer therapies, (Z)-Endoxifen does not target specific exon defects, potentially broadening treatment access for affected children.
Duchenne Muscular Dystrophy: A Rare and Serious Condition
DMD is a progressive, X-linked neuromuscular disorder resulting from mutations in the dystrophin gene. Common symptoms manifest in early childhood and include:
- Progressive muscle weakness
- Loss of ambulation
- Respiratory difficulties
- Cardiomyopathy
Despite advancements in treatment options, DMD continues to be a uniformly fatal condition in early adulthood, underscoring the need for effective, safe, and accessible therapies.
About (Z)-Endoxifen
(Z)-Endoxifen is an investigational SERM/D being explored by Atossa for applications in oncology and rare diseases. The proprietary oral formulation has demonstrated a promising safety profile and pharmacological distinctiveness from tamoxifen, including its unique receptor-targeted effects and protein kinase C inhibition. Currently, (Z)-Endoxifen is not approved for any specific indication.
